To all whom it may 00mm:

Be it known that 1, 'WILLIAM SGHAAKE, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Trolley Hangers, of which the following is a specification.

lily invention relates to trolley hangers and particularly to means for supporting a plurality of trolley conductors from a messenger cable.

The object of my invention is to provide a structure of the above-indicated character that shall be simple and durable in construction and be adapted for rigidly supporting a plurality of substantially parallel trolley conductors in rigid relation at predetermined points thereof.

, In practicing my invention, I provide similar clamping devices for the conductors that are adapted for co-operative relation with each other and a single means for clamping all of the parts in position.

Fig. 1 is an end View, partially in section, of a trolley hanger embodying my invention; Fig. 2 is a side view of the device as shown in Fig. 1; and Fig. 3 is an end view .of a modified form of trolley-hanger embodying my invention.

A hanger l for suspending a plurality of trolley-conductors 2 from a messener cable 3 comprises, in general, a plurality of sideby-side clamping members 4, that are held together by a transverse bolt 5, and a hangerrod 6 of U-shapethat is also held in position, with respect to the clamping members 4, by the bolt 5 and embraces the messenger cable 3.

The clamping members 4i are provided with jaws 7 that are adapted to engage the conductors 2 in a well-known manner. Each of the clamping members 4 has plane outer side faces 8 so that such members may fit snugly against each other and against the head 9 of the bolt 5 and a washer 10 that is located between one of the clamping members and a nut 11. The members 4: are provided with transverse central apertures 12 through which the bolt 5 extends, whereby any number of such members may be readily mounted side-by-side, in accordance with the number of conductors 2 to be supported.

Inside faces 13 of the members 4t are pro- Specifi cation of Letters Patent. Patented Jan. 31, 1922. Application filed February 4, 1518'. I senal'no. 215,333.,

vided with, oppositely disposed recesses 14: for the reception of the enlarged ends 15 of the hanger-rod 6, the ends 15 being held in position by the members 4 and thebolt 5.

Fig. 3 shows an adaptation of Inyinvention wherein three of the members 4 are used instead of only two, as in the other figures. Obviously, the device is readily applicable to any number of conductors, it being neces sary only to supply a slightly modified form of the hanger-rod 6.

' When it is two conductors, as in Fig. 3, by attaching the ends of the rod 6 to the outer clamping members, the intermediate recesses 14: may be occupied by a spacing lug 16 or the members at may be spaced apart in any other suitable manner. The bolt 5 thus serves as a single means to hold the individual mem bers 4 in engagement with their respective conductors 2 and to hanger-rod 6. 1

Vl hile I have shown and described a particular form of my invention, many changes may be made therein without departing from the spirit and scope thereof, as indicated in the appended claims.

I claim as my invention: I

1. A trolley-conduetor clamp comprising a hanger of substantiallyinverted U-shape for suspension over a messenger cable and having enlarged lower ends, a plurality of pairs of complementary trolley-conductor clamping cars disposed in side-by-side relation and having co-operating adjacent portions, said ears having complementary interior recesses for the reception, in. certain thereof, of said enlarged lower cndsof the hanger, and a single transverse bolt for holding the several pairs of ears in cool)- secure the same to the erative relation with each other, with the hanger and with trolley conductors to be supported.

2. A trolley-conductor clamp comprising a hanger of substantially inverted U-shape for suspension over a messenger cable and having enlarged lower ends, a relativelysmall spacing member, a plurality of pairs of complementary trolley-conductor clamping ears disposed in side-by-side relation and having co-operating adjacent portions, said ears having complementary interior recesses for, the reception, in certain thereof, of said enlarged lower ends of the hanger Fries,"

and in another thereof of saidspacing member, and a single transverse bolt for holding the several pairs of ears in cooperative relation with each other, With the hanger, with thespacing member and with. trolley conductors to be supported. I V

3. A trolley-conductor clamp comprising a hanger of substantially inverted U-shape for suspension over a messenger cable, a plurality of pairs of complementary trolleyconductor clamping ears disposed in side-byside relation and contiguousears of said pairs having eo-operating portions means for securing the, lower ends of the hanger to certain of said pairs of cars anda trans- 'erse bolt'extending through said ears for clamping all of the parts together. i

l A trolley-conductor clamp comprising a hanger for eo-operatioh with a messenger cable, a plurality of pairs of complementary trolley-conductor clamping ears disposed in side-by-side relation, said ears having means for the reception, in certain thereof, of said hanger, and a transverse memberfor holding'all of the parts together.

5. A trolley-conductor clamp comprising a hanger of substantially inverted U-shape forsuspension over a messenger cable, a plurality of pairs of complementary trolleyconductor clamping ears disposed in side-byside relation and having co-operating adjacent portions, and means for securing the hanger to thevclamping ears and for securing the ears to each other. V

6. A trolley-conductor clamp comprising a plurality of pairs of complementary trolley-conductor clamping ears disposed in side-byeside relation and having cooperating adjacent portions, and means for supporting and-securing the clamping ears to each. other.

In testimony whereof, I have hereunto subscribed my name this 31st day of Jan, 1918.:

WILLIAM soHAAKn.
